​Performance & Features

​The OPSJT14048 is built for users who need a balance between a small footprint and reliable extended backup.

• ​Extra Backup (XBD): This model is designed to provide 15–20% more backup than standard tubular batteries of similar ratings.

• ​Rapid Recharge: It features a special paste formulation that allows the battery to charge 15% faster than conventional jumbo batteries.
